TSU physicists are investigating the effects of radiation on DNA

Scientists from TSU's Laboratory of Experimental High Energy Physics and their colleagues from the University of Bordeaux are studying new ways of modeling the effects of low doses of radiation at the cellular level. For ...

The making of biorelevant nanomaterials

The interactions of biological macromolecules such as nucleic acids, proteins, and polysaccharide–protein conjugates can be mimicked by artificial polyelectrolytes. Such synthetic polyionic complexes are expected to serve ...

In-cell NMR: A new application

The structure of biological macromolecules is critical to understanding their function, mode of interaction and relationship with their neighbours, and how physiological processes are altered by mutations or changes in the ...

The PLOS Comp Biol Macromolecular Structure and Dynamics collection

Living systems are in a state of perpetual motion. Down at the microscopic level, the atoms that make up biological macromolecules are, in the words of Richard Feynman, jiggling and wiggling. These atomic motions are beautifully ...

Smart crystallization

A novel nucleating agent that builds on the concept of molecularly imprinted polymers (MIPs) could allow crystallographers access to proteins and other biological macromolecules that are usually reluctant to form crystals. ...

A closer look into the TSLP cytokine structure

The PROXIMA 2 beamline at Synchrotron SOLEIL recently celebrated its first birthday. It's an occasion to reflect back upon a year of the collaborative work accomplished and its high scientific impact. In particular, a recent ...

Green photon beams more agile than optical tweezers

Romanian scientists have discovered a novel approach for the optical manipulation of macromolecules and biological cells. Their findings, published in the European Physical Journal B, stem from challenging the idea that visible ...

NASA selects eight physical science research proposals

NASA's Physical Science Research Program will fund eight proposals to help investigate how complex fluids and macromolecules behave in microgravity. The investigations will be conducted aboard the International Space Station.
